What is the difference between Promise.all and Promise.any?

Promise.all waits for the completion of all promises in an iterable object. If all promises are fulfilled successfully, it returns a promise that resolves with an array of results in the same order as the input promises. If at least one promise is rejected, it returns a promise that rejects with the error of the first rejected promise.

Promise.any waits for any of the promises in an iterable object to fulfill. As soon as any promise is fulfilled successfully, it returns a promise that resolves with the value of that promise. If all promises are rejected, it returns a promise that rejects with an AggregateError, containing an array of errors from all rejected promises.

Comparison:

Criterion	Promise.all	Promise.any
Success condition	All promises fulfilled successfully	Any promise fulfilled successfully
Error condition	Any promise is rejected	All promises are rejected
Success result	Array of results (in the same order as input promises)	Value of the first successfully fulfilled promise
Error result	Error of the first rejected promise	AggregateError with an array of errors from all rejected promises
Usage	Dependence on all asynchronous operations	Dependence on any of the asynchronous operations
